2. California’s Renewables Portfolio Standard
 RPS signed into law in 2002 assigning roles to
Energy Commission, CPUC, and requiring retail
sellers to procure 20% renewable energy by 2010.
 Publicly owned utilities set their own RPS goals
recognizing the intent of the legislature to attain a
target of 20% of California retail sales of electricity
from renewable energy by 2010.
 Governor Schwarzenegger’s Executive Orders set
further goal of 33% renewable energy by 2020.
RPS procurement compliance is measured in terms of
electricity delivered, not signed contracts.

4. Energy Commission Work Related to
Renewable Energy
 All four divisions of the Energy Commission work on renewable energy.
– Siting of thermal power plants 50 MW and larger and transmission
planning for renewable energy.
– Policy development and implementation, including eligibility and
verification for the RPS; incentive programs for existing biomass,
small-scale wind, and new solar homes; actions to address barriers to
expansion of renewable energy; and climate change policy related to
renewable energy.
– Analysis of changes needed to electricity system to integrate high
levels of renewable energy.
– Public Interest Energy Research, including smart grid, storage,
renewable energy-based secure communities, mitigation of
environmental impacts of renewable energy.
 Collaboration/cooperation within the Energy Commission and with other
agencies at the state, local, and federal level.
 Experts and stakeholders help inform our work through advisory
committees, siting case hearings, public workshops, and support services
contracts.

6. Improving Processes for Licensing
Renewable Projects (E.O. S-14-08)
 “To implement and track the progress of the Executive Order, the California
Energy Commission and the Department of Fish and Game (DFG) signed a
Memorandum of Understanding formalizing a Renewable Energy Action Team
(REAT).”
 “… the Energy Commission, DFG, U.S. Fish and Wildlife Service, and the U.S.
Bureau of Land Management signed another Memorandum of Understanding
to establish a coordinated approach with our federal partners in the expedited
permitting process…”
 “ … the Energy Commission and DFG will identify renewable energy
development areas and develop a best management practices manual with the
goal of reducing the application time in half for specific renewable projects 50
MW and greater proposed in the designated renewable energy development
areas.”
 “To initiate Natural Communities Conservation Plans (NCCPs) … REAT will
begin the Desert Renewable Energy Conservation Plan for the Mojave and
Colorado Desert regions… This should also help reduce the time and
uncertainty normally associated with licensing new renewable projects.”

credibility of the "green" value of renewable electricity
 WREGIS is a voluntary, independent renewable
energy registry and tracking system for the CEC ROLE
Western Interconnection transmission area  Certify renewable facilities as
eligible for the RPS

certificates
 WREGIS was launched in June 2007
 Retail sellers and renewable facilities participating in California’s RPS are

Major challenges continue to exist for renewable development
and moving the state to 33% renewables by 2020.
 Difficulty integrating large amounts of renewable energy into the
electricity system.
 Uncertainty on timeline for meeting RPS goals.
 Environmental concerns with development of renewable facilities
and associated transmission.
 Difficulty securing project financing.
 Delays and duplication in siting processes. Time and expense of
new transmission development.
 Cost of renewable energy in fluctuating energy market.
 Maintaining state’s existing baseline of renewable facilities.

14. 2009 IEPR Commission Final Report:
Key Recommendations for Renewable Energy
 Continue the cooperative work among state agencies to implement a
33% renewable policy that applies to all load serving entities and retail
providers.
 Reduce regulatory uncertainty with legislation to codify the 33%
renewable target.
 Implement measures to accelerate permitting of new renewables and
associated transmission.
 Address barriers to the expansion of biopower, including regulatory
hurdles and project financing, and encourage R&D to reduce costs for
biomass conversion, biopower technologies, and environmental
controls.
 Identify solutions to integrate increasing levels of energy efficiency,
smart grid infrastructure, and renewable energy while avoiding surplus
generation.
